ACNU-250L-000E数据手册Broadcom中文资料规格书

描述 Description

ACNU-250L is a single-channel 1MBd optocoupler device in an 11-mm stretched SO8 package. The device is equipped with an insulating layer between the light emitting diode and integrated photon detector to provide electrical insulation between the input and output. Having separate connections for the photodiode bias and output transistor collector reduces the base-collector capacitance and enhances the data speed up to a hundred times compared to a conventional photo-transistor coupler.
ACNU-250L is suitable for isolated communication logic interface and control in high-voltage power systems, space-constrained industrial applications, renewable inverters and medical equipments. This package platform features wide 11-mm creepage and 10.5mm clearance, high insulation voltage of Viorm = 1414Vpeak and a compact footprint which is 40% smaller than the 400mil DIP8 package.
